目前数字水印技术的研究和文献主要集中在静止图像和视频的保护等方面,文本数字水印研究的很少,国内甚至还未见到文本数字水印的相关文献。而实际上,一些文本文档比图像、视频等更需要得到保护;数字文本的保护对互联网时代的政府工作和电子商务等也具有重要意义。本文主要介绍文本数字水印技术的基本思想和目前的研究状况,首先介绍了文本数字水印的嵌入与检测方法,然后分析了用于中文的文本数字水印的研究方向以及可能的应用前景。
Abstract
Presently the researches and literatures on the technology of watermarking are mainly focused on the protection of still images and video documents.But few researchers’interests are in the watermarking of text document . In China ,there is even no literature on this area.But in fact , some text documents are more necessary to be protected than images and video documents. And protecting digital text documents is very important for the work of government and electronic business in the era of Internet . In this paper we mainly introduce the base idea and present research actuality about watermarking for text documents. This paper shows some methods for embedding and detecting watermark. Then the research direction and possible prospect of the digital watermarking for Chinese text documents are analyzed.
